A desktop experiment has been done to show the nonlinearity in the I-Vcharacteristics of an ion conducting electrochemical micro-system. Its chaoticdynamics is being reported for the first time which has been captured by anelectronic circuit. Polyvinylidene fluoride-co-hexafluoropropene (PVdF-HFP) gelelectrolyte comprising of a combination of plasticizers (ethylene carbonate andpropylene carbonate) and salts have been prepared to study the exchange of ionsthrough porous poly ethylene terephthalate (PET) membranes. The nonlinearity ofthis system is due to the ion exchange of the polymer gel electrolytes (PGEs)through a porous membrane. The different regimes of spiking and non-spikingchaotic motions are being presented. The possible applications are highlighted.
